Bibliometric analysis of research trends and characteristics of oral potentially malignant disorders.

OBJECTIVES

The term oral potentially malignant disorders (OPMD) was recommended at the WHO workshop held in 2005 and published in 2007, and increasingly large number of papers related to OPMD are published. The objective of the bibliometric analysis was to investigate the citation characteristics and analyze research trends of OPMD.

METHODS

A comprehensive search was performed and identified in the Scopus database since 2007 for the bibliometric list of OPMD in the syntax.

RESULTS

A total of 795 papers on OPMD were retrieved and the total number of citations was 8870. The mean number of citations is 11.2, with a range of 0 to 580. A substantial increasing tread in the number of citation is observed since 2007. Leukoplakia (42%) and lichen planus (23%) were the two most individual disorders among the general OPMD. A controlled/comparative study (43%) and a retrospective study (16%) were the two most study designs. India (n = 267) and the UK (n = 99) were the two most contributing countries. Tobacco and alcohol use and betel quid chewing (n = 351) are the most common keywords. Notably, early detection and diagnosis of oral cancer (n = 255) and biomarkers of oral carcinogenesis (n = 178) top the list, which may indicate a trend of key topics.

CONCLUSIONS

The current study for the first time reported the bibliometric characteristics and research trends of the papers on OPMD in the syntax.

CLINICAL RELEVANCE: The bibliometric analysis highlights the key topics and studies which have shaped the understanding and management of OPMD.
